AEM Wideband UEGO Controller
06-17-2004, 06:40 PM
Does anyone know if there is another wideband UEGO controller that will work with the AEM EMS; I'm guessing probably not but doesn't hurt to ask. My buddy wants to get one and I see Gauge-Type one and a non-gauge one in either single or dual band version; anyone have a clue what the difference is (other than the gauge) or which one would be better? He's running like 16+ psi and wants to crank up the boost but doesn't want to have to go all the way to Virginia again (from NY) to get it tuned and would rather just tune it on a dyno himself. Any help is greatly appreciated.

look into plx devices. they have wireless datalogging models now. more expensive than the aem of course. why not go with the aem?

Yeah I think he's just going to go with one of the AEM ones. He was jsut hoping to find something cheaper. He's spent so much $ getting the thing to run and it's been nothing but one problem after the other; he says he's going to get it running good and sell it and get a crotch-rocket. I just think he went about things the wrong way (h22 w/T25 turbo=bad combo) and he's just not happy with it...no sh*t ya know.

well he's gonna have to spend that much unless he uses a narrow band but that serves no purpose in tuning. i BELIEVE there are other wideband that are cheaper and work ok but they look like something a 2 year old put together with a board and leds. there are also DIY wideband ones but after purchasing all the parts it's cheaper to purchase one. i suggest purchasing a plx one with just digital display and selling it afterwards. they're cheaper than the AEM.

Oh sweet the PLX one should be exactly what he's looking for, it even has the details on how to hook it up to the EMS. Thanks man I really appreciate it.

they're actually not that expensive .. digital readout and all ... and i bet he could sell it off easily after the tuning. hell i'd even buy it! haha. good luck.

PLX devices are a lot cheaper then cheaper than the AEM ones.

If he has an AEM EMS in his car you can go down to napa, buy a bosch wideband O2 sensor, brill and weld a bung, plug it in, and configure your AEM for it, it's not that hard. You're going to be tuning with a laptop anyways, why waste 400 bucks on a little display with a serial cable?

I got the AEM and it is hot....that PLX thingy looks like an atari accessory. The AEM is work the extra $100.00 and its fun to look at....it even has an autodimmer. The only this is you are probably gonna have to cut a hole in your header or exhaust or downpipe (if u have one) because the sensor is alot thicker than the factory one and weld the bung in like jcrx said. I dunno.....I like to stick to the same manufacturers as much as possible

Hey jcrx.....what Full-Race Stage do you have on your civic?
06-19-2004, 05:19 PM
Huh? Um, no Full Race anything, N/A here.

oh shit sorry....I meant boosted331...my bad

Well... my buddy's been having a lot of trouble with the EMS, so much now that the thing wouldn't even start. He got it professionally tuned and everything, didn't mess with anything without putting it back the way it was. So he put in his stock injectors (was running 550's i believe) and ECU and the thing is running like a champ. So he decided to just sell the EMS and get an Vortech FMU (told him this was a bad idea from what I've read online.) I don't know maybe the guy he went to get it tuned from messed something up. YellowITR479 have you had any problems with the EMS at all; like running way too rich all of the sudden or RPM's jumping all over?

Im not running an EMS cause it was too much $$ and that it would cost twice as much to tune that a Hondata...which is what I have. I got mine off E-Bay for $550.00 and it had the datalogging option with an OBD-1 ECU. I have also heard some negative stuff about the EMS....mainly from people that have Acura's/Honda's. I know 1 person that run a EMS...on a fully built Supra....and his car runs like a gem with only minimal tuning. I dont know...maybe AEM has some defective units. I have not heard too much negative stuff about Hondata

Oh ok I misunderstood you when you said "I got the AEM and it is hot...." I didn't realize you ment the wideband. Yeah I know another guy with it on his Evo and his is idling like shit too. I've been trying to talk my friend into just getting hondata but he's stuburn. Thanks for the input.

it might have a rough idle because the low speed/idle fuel maps and such weren't nailed down when tuning.. it's all about the quality of the tuner i've heard..
